Congratulations for the excellent video, which improves the previous one by adding BorderSize, BorderStyle and BorderSide. Thanks very much

Greetings. Unfortunately I have to revise my comment. I didn't realize that the controls flicker quickly when taking and leaving focus. It can also be seen clearly at the end of the video, when you write inside the three textboxes. Evidently there is a problem in the control painting. As it is, though, it's very annoying, and a user using a program with these controls would definitely not like it. Is it possible to avoid this flickering? Thank you
